I have no idea where they were made.

I think either you did not read my 1st post, or you are trying to screw up something I have for sale.

I am offering these kits. I am trying to sell something. My price is half of garage SPEC's.

If you think you can get 18-8 stainless steel M6x1.0 hex-drive screws (QTY 6) and 18-8 stainless steel countersunk washers for them (QTY 6) for less than $20 without having to buy them in bulk ... I suggest you knock yourself out and go buy them.
